Lane Change Information Presentation Device for Vehicle Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques, such as those described in PTL 1, fail to effectively assist drivers in determining whether it is safe to change lanes, often leading to difficulties in responding to irregular situations and hindering smooth vehicle progression.
Innovation Solution
An information presentation method and device that acquires peripheral vehicle information, determines the safety of lane changes based on this data, and presents the results to the driver, using sensors like LIDAR, cameras, and GPS, with visual and auditory feedback through a display or speaker.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If automated determination is used for lane change decisions, then response speed is improved, but adaptability to irregular situations deteriorates
Solution Approach 1:
The system introduces an information presentation device as an intermediary between the automated determination system and the driver. This mediator provides situational awareness information and determination results to the driver, enabling the driver to make informed decisions while maintaining the speed benefits of automated sensing and analysis. The intermediary resolves the contradiction by combining automated processing with human judgment.
2Reliability
If warning is issued to stop vehicle progress, then safety is improved, but smooth progression of vehicle deteriorates
Solution Approach 1:
The system dynamically adjusts its intervention level based on the determination result. When the lane change is determined to be safe, the system provides information and allows smooth progression without interruption. When unsafe, it issues warnings to prevent dangerous maneuvers. This dynamic response resolves the contradiction by applying safety measures only when necessary, maintaining smooth progression when safe.
3Measurement precision
If detailed object information is acquired for lane change determination, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The system employs multi-functional sensors (LIDAR, cameras, radar) that can detect various types of objects and provide multiple parameters (position, speed, distance) simultaneously. These universal sensors resolve the contradiction by providing detailed measurement precision through a single integrated system rather than multiple specialized devices, reducing overall complexity while maintaining high detection accuracy.

AI summary
Provided is an information presentation method capable of, when a vehicle tries to enter a second lane different from a first lane on which the vehicle is traveling, effectively presenting information for assisting situation determination by a driver. The information presentation method for presenting information for assisting situation determination by a driver of a vehicle includes: acquiring information about an object located in a periphery of the vehicle; determining whether or not the vehicle can enter a second lane different from a first lane on which the vehicle is traveling, based on the information about the object; and presenting a result of the determination to the driver.
